To 'all-whom 'it may-concern: j

Be it known that l, `EDWARD COURT, acitizen4 of the United States, residing at Milwaukee, in the county ofl Milwaukee `and State of Wisconsin, have invented certain new and useful Ii'nprovements in Spindles forv Bottle-Washing Machines, of which the following is a specification, reference being had to the" accompanying drawing, forming a part thereof.

This invention relates broadly to improvements in bottle washing machines, but more particularly to improvements"` yin brush spindles employed in suchmachines."

My invention has for `its-object the provision in abottle `washing' machine employing brushes or like cleaning means, of. an improved spindle which acts to compensate for the wear on the brush and to positively force the same into Vproper contact with the bottle to be cleaned so as to insure eective cleansing of each bottle passed through the machine. M c

The present improvement `is especially adapted for use in those machines wherein the brushes receive only a rotary movement and the bottles are bodily moved tov bring them into position to receive pthe brushes, the bottle carrier receiving a predetermined, limited movement., Through continued use the ordinary brushes wear down `or Vare broken off with the result that theyv fail to properly contact with and cleanse the bottles and especially 'the bottoms thereof, which necessitates the frequent removal `of the worn brushes and substitution of new ones. wear is automatically compensated for by the method of mounting the brushes and the construction of the spindles, as will vappear hereinafter. The advantages thereby obtained are twofold, increased utility Vof each brush and the certitude of thorough cleansi ing in spite ofthe wear on the brush.

The vmeans by which these objects and advantagesare obtainedwill be moreparticularly. described inthe following` specification and are .illustrated in the accompanying drawing showing thepreferredV embodiment of'myvimprovement, in which e Figure 1 is a'sideelevation of a bottle washing machine,.with parts broken away, showing an adaptation of my vimproved spindle thereto; Fio. 2 is an elevation showing ythe spindle wIthn brush attached; and

By my improvement yhowever this,

cleaned.

Eig. 3v isa vertical section of the spindle and brush holder.

With more particular reference to the drawing, especially Fig. 2 thereof, a brush l of bristles, or other suitable material, is secured by means of a core `2 topa suitable hollow brush-holder 3. As seen in Fig. 3,

` this holder 3 is provided with a water pasvcontact with the lower closed end of the slot. The pin 8 limits' the upward and v downward movement ofthe plunger 7 and secures the same within this spindle 6. By removing .pin 8, the plunger 7 may be detached from the spindle 6 when desired.

The upper end 'of the plunger 7 is screwthreaded externally to receive the threaded portion of the brush-holder 3, which is thus removably .mounted` thereon and may be readily detached to replace a worn brush with a new one or for' purposes of repair.

' Surrounding the plunger 7 is a spring 9, one-end of which abuts against a collar 10 4formed externally on the plunger 7, and the other end rests upon the upper end of spindle 6. The action of this spring 9 is to continually and to positively force the tubular plunger 7, and hence the brush supported thereby, upwardly to the limit of its movement, as regulated by the pin 8 traveling in slot 7 of the plunger.

As the brush carried by the reciprocating plunger 7 becomes worn and shortened by constant usage, the spring 8 compensates for this wear and insures the proper contact of the brush with the bottom of the bottle being It is clear that in the ordinary bottle washing machine wherein the bott-les receive a predetermined and limited movement, andthe brushes are given simply a `rotative movement, through constant use the lconstruction herein described this disadvantage is removed and the effectiveness of this class of machines improved.

In Fig. 1 I have shown my improved spindle in use in a bottle washing machine of a well known type, sutlicient parts of the machine only being shown to illustrate the operation. The spindle 6 is mounted for rotation, being driven through gear 11 mounted on the base plate 12 of the machine. The brush 1 carried by the spindle 6, when the machine is not operating, rests within the sleeve 13 of the lower bottle supporting plate 14. The plates 14 and 15 receive the bottle 16 therebetween. The bottle 16 is clamped between the plates 14 and 15 by operating a suitable lever 17 mounted on the shaft 18 and secured to plate 15, which forces plate 15 downwardly into contact with the bottle and locks it in this position. Both plates 14 and 15 are mounted Jfor reciprocation on guide 19 by means of collars 20 and 21 respectively. These plates 14 and 15 constitute the bottle carrier and are given a vertical reciprocatory movement in any well known manner through the medium of the operating crank 22 and the rod 23. To the rod 23 is connected a collar 24 which engages the plate 15, while the collar 20 of plate 14 is provided with an extension 25 connected to the rod 23. The bottle carrier receives a limited downward movement through the crank 22 and rod 23, which carries downwardly the sleeve 13, thereby liberating the brush l and bringing the interior of the bottle into contact therewith. In the lowered position of the carrier, the bottle bottom presses against the brush 1 and acts against the pressure of spring 9 so that good contact between the bottle bottom and brush is secured. The brush 1 being spring pressed thus constantly assumes the best and most effective operative relation to the interior of the bottle in spite of any wear that may be occasioned by constant use.

Other means of accomplishing the objects of my invention may be suggested by this description of the preferred embodiment thereof, andvarious changes may be introduced to attain these ends, but are believed to fall within the scope of this invention.

What I claim and desire to secure by Letters Patent of the United States, is

1. In a bottle washing machine, a rotary spindle, a reciprocating member mounted therein, having a slotted lower portion, a removable brush holder secured to said member, a resilient means mounted upon the spindle and engaging the reciprocating member, providing a yielding support for the brush holder, and removable means engaging in said slotted portion to limit the movement of the reciprocating member, substantially as described.

2. In a bottle washing machine, ay rotary spindle, a tubular support mounted for reciprocatory movement therein, and having a vertical slot, a brush holder removably mounted thereon and provided with a brush, means for limiting the movement of the snpport, engagingl in the slot thereof and a spring carried on the spindle and engaging the support and normally acting to hold the latter at the limit ot' its upward movement, substantially as set forth.

In witness whereoiI I hereto atiix my signature in presence of two witnesses. i
